RIDING ATTACHMENT FOR I-IARROVIS AND THE LIKE.

To @ZZ 'Lv/wm. it may concern.'

Be it known that I, CHARLES Sr SHARP, a citizen of the United States, residing at Auburn, in the county'of Cayuga and citate of New York, have invented certain new and useful Imnrovements in Riding Attachments for Harrows and the like, of which the following is a full, clear, and exact specification.

ily invention relates to riding attachments for harrows and thelilie.

It has for its object to provide a riding attachment of improved and simplified construction. A further object of my invenion is to provide a riding attachment especially adapted to use on side hills, which is automatically maintained in the'desired relation to the harrow and team as the harrow tends to slide downward on the side hill. I attain these objects by the provision of an improved construction wherein the drivers weight is carried at points back of the axles of the riding attachment, and these axles are operatively connected to the harrow in such an improved manner that the wheels of the riding attachment are automatically turned up the hill to maintain the riding attaehment. in the desired position as the harrow slides downward. These and other features of my invention are hereinafter described.

In the accompanying drawings I have shown one embodiment which my invention may assume in practice. It is to be understood, however, that the forni shown herein for purposes of illustration may be modified without departing from the spirit of my invention.

Figure 1 is atop plan View of a harrow equipped with this form of riding attac-hment. the position of the parts in turning at the end of a iield being shown in dotted lines.

Fig. 2 is a rear elevation of the riding attachment.

F ig. 3 is a detail view taken substantially on line 3 3 of F ig. 1 showing the locking mechanism.

Fig. et shows a plan view of a harrow and attachment embodying Vmy invention, with the parts in the position normally occupied on the side of a hill;

action of the forces tending to turn vthe wheels of the cart up-hill when the device is being operated on a side hill.

In the construction shown I have illustrated diagramatically a harrov.r 1 of the peg tooth type provided with suitable draft connections 2 and formed of a plurality of units flexibly connected to the ends of the draft member 2 through intermediate draft members 3. lhe riding attachment hereinafter described is trailed at the lrear of this harrow.

Pivo tally connected at their front ends to the inner ends of the members 3 through any suitable flexible connections, such as eye bolts el, is a plurality of forwardly extendingdiverging draft members 5 of this riding ataclnnent. The rear ends of these draft members are rigidly connecten at 6 at points intermediate the ends of a transverse frame .member 7. This frame member 7 is pivotally connected its ends at 8 te the front ends of a lpair oit short converging linhs which are integrally connected to the stubv axle members 1() of the riding attachment. As shown, these axle members 10 are provided with forwardly and inwardly projecting integral arms 11 to which the links 9 are iixed, and are provided with laterally ex tending portions lz of reduced diameter and cylindrical cross section on which wheels i3 of the riding attachment Vare rotatably mounted. it a point in the rear ofthe body of the axle members 10 and adjacent the hubs le of the wheels 13, upstanding rearwardly protruding lugs or extensions 15 are provided on these axle members having vertical bores therein adapted to receive and form bearings for upstanding projections 16 on the opposite ends of a transversely extending rod 17. The upper ends of the proiections 1 6 on Vthis rod, which protrude through the lugs 15, are attached to a flatl seat supporting member 18 by `I'neans of cotter pins 19. It is to be noted that the seat supporting member 18 is disposed in a plane above the connecting` rod 17 parallel thereto and that a seat support 2O is carried on the upper surface thereof and attached thereto at points intermediate its ends by suitable bolts 21, a seat 22 being car 'ied on the top of the seatsupport 2O in the usual'manner.'

It is to be noted that in thisv construction the weight of the operator is carried *at a A rat-enten Feb. 2e, 191s. Application led August 27, 1913, Serial No. 786,961. vRenewed. December 10, 1915.

point back of the axles l0 so that the tendency of the operators weight when operating on a side hill is to cause the wheels 13 to swing up the hill toward the 'position shown in Fig. l, the operator thus beingl maintained in the desired relation with respect to trie team and the barrow. is shown in F ig. 5, when the cart is being operated on a hillside, laterally inclined, the center of the weightl or the driver, represented by lines :lt-3, `lialls to one side of the central portion ot the piroted seat supporting bar 18. il downward and lateral thrust in the direction ot the lines *C* 1 is Vthus imparted to the pivotal points l@ of said seat supporting bar. The result-*ig` action is as she vn in the diagram in l D 6, where it will be seen that the torce of the seat supporting bar, represented the dotted lines E-F, t'alls to the rear of the center of the wheel or ground engaging` center thereof, represented by the letter rlhe seat supporting bar thereby has a leverage tending to turn the wheel uphill, the ement of this leverage being represented by the dotted line l-J. The end lthrust or the bar 18 being thus transmitter to the wheel through the levers E-F and lull, the wheel tends to turn about. its ground center il, moving the axle arms 9 about the arcuate path l-L while the pivotal connection l5 is moved through the path lll-N. Such is tlie theory of operation of the automatic guiding` olthe harrow cart. However, in practice, it is only necessary to apply a lateral torce to the wheels rearwardly of their ground engaging centers, and they immediately assume an up-hill direction. By thus maintaining the cart well upward on the hill, the driver is kept in a central line with the draft animals and a torce is transmitted through the draftA arms to the draw beams 2 and 3, which will tend to hold them in right angular position with respect to the line of lraft. 'rlhe drag sections will thus be heln against sliding' t own hill except vto the limited extent permitted by the flexible link connections between each section and draftbeam.

ln order that when operating on level ground the operator may locl; Vthe riding at tachment so that the wheels 13 will not readily swing laterally, but will be maintained in comparatively rigid relation with respect to the frame, l have provided an improved locking mechanism. rlhis locking mechanism is shown to comprise. a substantiallj,Y U-shaped band Q3 which is bolted at its rear ends by means of bolt Qlito the connecting rod 17 and the seat supporting rod 18, the bolt extending through both of these rods, as shown in 3, at a point substantially halt way between the ends thereof and directly under the operators seat 22. The front end of this U-shaped locking member is adjustably pivoted by a bolt and lock-nut 25 to the front frame member 7 and to a suoplcmental trame member Q6 which is rigit y connected to the inner ends ot' the drai mem1 ers 5 in a plane above the member Y by the same means which attach the inner h r'w ends of the drait members o thereto. lhe

more or a plurality olf foot rests located f inside the draft members 5 and at a point in front and below the seat.

lt is to be noted that the construction illustrated is entirely automatic in its action, the weight of the operator acting automatically to swing the wheels as the barrow strikes the side hill ano maintain the operator in the desired relation with respect to the harrow and the team. When the cart is being operated on level. ground, the locknut or bolt 25 may be so adjusted that tho wheels will not respond to slight changes in the inclination ot' the ground such as would be caused by ridges or ditches, but in turning at the end of the field will yield to permit the wheels to angle as shown in dotted lines in Fig. l. lVhen, however, the cart is being used on a hillside, the loci-.ing mechanism may be so loosened that it will in no wise restrict a free movement of the wheels as is desirable in order that theA weight of the driver may control the pivotal. action thereof. rl`his same U-shaped strap because of its swinging movement, may obviously be utilized as a support tor a torwardly extending seat bracing member (not shown), after the manner shown in some ot my prior patents, notably No. 9OT,lS5. December' 92, 1908. lt is also to be noted that the construction is exceedingly simple and rugged and that due to the location of the operatorie weight, no strains placed upon the same tending to produce warping in service, and the drag upon the team is i'ninimized.

lllhile l have in this application described onerembodiment which my invention may assume in practice, it is to be understood, of course, that the form shown herein for purposes of illustration is susceptible of modilications without departing from the spirit of my invention.
